[PATCH 3/3] gpio: pca953x: use the correct register address when regcache sync during init

[haibo.chen@xxxxxxx]

From: Haibo Chen <haibo.chen@xxxxxxx>

For regcache_sync_region, need to use pca953x_recalc_addr() to get
the real register address.

Fixes: ec82d1eba346 ("gpio: pca953x: Zap ad-hoc reg_output cache")
Fixes: 0f25fda840a9 ("gpio: pca953x: Zap ad-hoc reg_direction cache")
